ALLU high-capacity coal bucket: in-pit processing gains for mine engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
ALLU is introducing a new high-capacity coal bucket designed to process coal and associated waste rock, clay and other impurities directly on smaller carrier machines, cutting out separate loading, haulage, crushing and screening stages. By integrating sizing and impurity separation at the face, the attachment targets in-pit coal conditioning where conventional fixed or semi-mobile crushers are impractical or underutilised. The concept is aimed at reducing double-handling, shortening haul distances and enabling more flexible deployment on smaller excavators or loaders in constrained pits and stockyards.
Technical Brief
- Bucket configuration is tuned for coal seams containing harder waste rock bands and plastic clays.
- Attachment is designed to tolerate variable feed, from soft coal to abrasive gangue, in a single pass.
- Geometry and aperture selection target coal sizing suitable for downstream plant without secondary crushing.
- Wear-resistant materials and replaceable components are expected to manage high abrasion from silica-rich waste rock.
- Direct face processing reduces stockpile contamination by segregating clayey fines and hard bands at extraction.
Our Take
Coal appears in only a small subset of the 65 keyword-matched pieces in our database, signalling that new coal-processing products like this ALLU bucket are now relatively niche compared with the dominant focus on critical minerals and decarbonisation themes.
International Mining also features in coverage of Global Air Cylinder Wheels’ alternative OTR wheel technology and Sandvik’s postgraduate mining programme, indicating that this outlet is increasingly a platform for both equipment innovation and skills development content rather than just project case studies.
For coal operators, higher-capacity processing on smaller carrier machines typically matters most in thin-seam or satellite pit work, where our project coverage shows a consistent push to cut rehandling and mobile fleet size to keep marginal tonnes economic under tightening emissions and cost pressures.
